Diagnostics
Property Techniques
A property diagnostic involves conducting a study in a building to check the installations or the presence of harmful materials. The aim is to inform potential buyers about the characteristics and condition of the property for sale.
The seller must present a series of diagnostics that are in a state of validity to sell the property. The documents gathered by the owner must be attached to the preliminary sales agreement as well as to the deed of sale.
Diagnostics are merely an obligation to inform: regardless of the results, the sale can proceed, and the seller is never required to carry out any work.
Here are the 10 mandatory property diagnostics to be carried out by the seller for the buyer in 2026 in France:
1. Energy Performance Certificate (DPE)
(Diagnostic de performance énergétique)
The DPE informs the buyer about the property’s insulation. Mandatory – Validity 10 years. To be redone in case of substantial works.
2. Carrez Law Measurement
To sell a property that is part of a co-ownership, the Carrez law measurement is necessary to define the living area. Mandatory – Unlimited validity except in case of works.
3. Electrical Diagnostic
The electrical diagnostic aims to verify whether the panel and the rest of the installation meet standards. Mandatory for any property with electrical installations over 15 years old – Validity 3 years.
4. Gas Diagnostic
This diagnostic checks the condition of the gas installation. Mandatory for any property with a natural gas installation over 15 years old – Validity 3 years.
5. Asbestos Diagnostic
Indicating the presence or absence of asbestos. Mandatory for any building for which the building permit was issued before 1st July 1997 (the date corresponding to the prohibition of using this material). Unlimited validity if no trace of asbestos is detected. If asbestos is detected, a new check must be carried out within 3 years following the issuance of the diagnostic. If the diagnostic was conducted before 2013, it must be renewed in case of sale of the property, even in the absence of asbestos.
6. Lead Diagnostic – CREEP
Old paints containing lead are toxic, thus requiring a diagnostic. Mandatory for any property completed before 1st January 1949. Before this date, lead was indeed used in the composition of paints of that time – Unlimited validity if no trace of lead is detected – 1 year if lead presence exceeds certain thresholds.
7. Termite Diagnostic
The parasitic state concerning termites can be mentioned via this diagnostic. Mandatory for any property located in a contaminated or potentially contaminated geographical area. Decided by prefectural decree. To know the affected departments, consult the map of departments covered by a prefectural decree in 2012 – Validity 6 months.
8. Natural and Technological Risks
The ERNMT (État des Risques Naturels, Miniers et Technologiques) allows you to see if the property is located in an area exposed to risks (flooding, seismic…). Mandatory – Validity 6 months.
9. Sanitation Diagnostic
Controlling sanitation installations. Mandatory for all properties with an individual sanitation system – Validity 3 years.
10. Information on Dry Rot
All built properties (areas defined by prefectural decrees). Mandatory – Validity: No fixed duration.
